7.0 Startup and Operation
Installation Review
Prior to Startup
Once the mounting, cabling, and alarm relay installation has been completed, the IPES IR3 is ready to begin the
power‐on sequence.
Before applying power to the system for the first time, review the steps below:
•
Verify that the IPES IR3 has been properly mounted.
•
Verify that all conduit / cable gland entries have been tightened and sealed if necessary.
•
Verify that all sensor wiring has been installed correctly.
•
Verify that the enclosure has been connected to an earth/ground.
•
Verify that the IPES IR3 cover is securely installed
•
Disconnect or power down all output devices and alarms to prevent false actuation.
Once you are ready to begin startup, verify that the power supply is connected properly and verify the power supply
voltage with the IPES IR3 is disconnected at the source. The IPES IR3 is powered by 24 VDC (18 to 32 VDC voltage range).
Performance Test
After installation is complete, conduct a performance test as follows, to ensure that the detector is functioning properly.
Test Equipment
ESP Safety, Inc.’s ITES Dual‐Test Lamp (part number 120‐0007) is designed to assist in the functional testing
of the
detectors without the need to remove the detector from the application. The Test Lamp generates directed modulated
radiation with sufficient intensity to signal a flame or fire response to the detector, indicated by a flashing red LED on the
IPES‐I
R3.
Each Test Lamp is supplied pre‐asse
mbled with an emission source, housing, batteries, and an Operating Manual.

Power‐On Self‐Test
After s
upplying power to the detector (24VDC +/‐8VDC) the unit will perform a self‐test
procedure
1.
When power is applied, the status indicator led lights up for 3 seconds in a solid yellow color. In three seconds, the
status led will blink yellow for 7‐8 seconds, after this, the self‐testing of the device
starts (three self‐test lamps
beneath the cantilevers of the optics window will flash three times).
a.
The ‘Working order' relay (R_WORK on the IPES‐IR3 X3 receptacle) will be open (Fault Indicat
ion) during
p
ortions of the initial self‐test cycle.
b.
The 4 to 20mA output will be at 2.0mA indicating the IR 3 is in the power on mode
2.
After the self‐test,
the LED will glow with a solid color depending on the test results: yellow
‐test failed,
green
‐the
device is operable
